DRAFT-EQUALIZER.

SPECIFICATION forming part of Letters Patent No. 707,539, dated August26, 1902.

l Application filed December 28, 1901. Serial No. 87,557. (No model.)

To all whom ift may concern.;

Beit known that LTHoMAs WESLEY BANTA, a citizen of the United States,residing at New Richmond, in the county of Montgomery and State ofIndiana, have invented a new and useful Draft-Equalizer,of which thefollowing is a specification.

This invention relates generally to draftequalizers, and moreparticularly to one intended for use in connection with gang-plows; andthe object of the invention is to provide an exceedingly cheap andsimple appliance which can be attached to any gang-plow now in use andwhich will enable the draft to be applied to one side, taking off allside draft, thereby enabling the horses to travel with a direct draftand affording them all the room they need in which to travel. It alsoeliminates all friction on the landside, thereby making the draft muchlighter.

Another object is to provide a device which will yield when any unusualtension is placed thereon-such as may be caused by the plowpoints comingin contact with a stump, rock, or other obstruction-thereby avoiding thebreakage of any other parts of the plow.

With these objects in view the invention consists in the novel featuresof construction and combination hereinafter fully described, and pointedout in the claims.

In the drawings forming part of this specilication, Figure l is aperspective View showing the practical application of my invention. Fig.2 is a top plan view of the same. Fig. 3 is a detail sectional view onthe line 3 3 of Fig. 2, and Fig. 4c is a detail perspective view of theslotted link and folded strap to which the said link is connected.

Referring to the drawings, A indicates the plow-beams, connected attheir forward ends by means of a cross-clevis B, said plow-beams A andcross-clevis B being braced by means of the angular straps G, secured tothe inner faces of the said beams, and the laterallyprojecting end ofthe cross-clevis B is further braced by means of the brace strap or bandD, which extends from the end of the said projecting portion to the sideof the adjacent beam A.

A clip E is rigidly secured to the end of the cross-clevis B, said clipE having a bolt passing through its center for the purpose of holdingthe clip to the cross-clevis, said clip E having a draft-@levisconnected thereto by a long bolt standing up and down, and thedraftclevis which stands up and down is connected with the maindoubletree-clevis F. A hook .II is connected with the same bolt thatconnects doubletree-clevis With up-aud-down clevis, said hook or eyehaving a link I connected thereto, the opposite end of said link beingloosely connected to a slotted bar or plate l, said slotted bar or platebeing arranged between the ends of the folded metallic strap L, a bolt Lpassing through the ends of the strap andthrough the slotKQ produced inthe bar or plate, said bolt having a'nut L2 upon its lower end and bymeans of which the slotted bar or plate, which virtually constitutes alink, can be secured between the ends of the folded strap or band,thereby producing a rigid connection between the link I and the foldedband or strap L. A twisted link M connects the folded band or strap L toa spring-bar N, the said link M engaging an eye or loop N', producedupon the end of the said spring-bar, the opposite end of said spring-barbeing attached to the side beam A and passing around the end of thecross-clevis B, as most clearly shown at N2. By means of draftlappliance constructed and arranged as herein shown and described I amenabled to place the draft entirely at the side, and more room isthereby provided for the horses,`which enables the plows to take theproper ainountof land, thereby enabling the horses, plows, and gangs totravel in an easy unstrained condition. In case the plowshould strike astump, rock, or other obstruction the excessivestrain placed upon thedoubletree will cause the slotted bar or plate to slip between the endsof the foldedV strap L and all damage to the other parts of the plowwill be avoided. The slotted plate can then be readj usted and theplowing operation resumed.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

l. The combination with the plow-beams and cross-clevis, a draft-clevisattached to the end of said cross-clevis, a spring-bar connected to theend of said plow-beam around the end of cross-Clovis and the yieldingconnec- ICO tion between the side draft-clevis and the end ofspring-bar, substantially as set forth.

2. The combination with the plow-beams and cross-clevis, one end of saidcross-clevis projecting laterally beyond the plow-beam, of adraft-clevis attached to the projecting end of the crossclevis, aspring-bar connected to the opposite end of said plow-beam A', ayielding connection between the said spring-bar and draft-devis, saidyielding connection comprising a twisted link,4 a folded strap or bar, alongitu dinally-slotted plate, and an angular plate having a hook at oneend, substantially as described.
